Got banned over there a month ago, came here hoping to find something of a Sonic community in the same vein as the one over there (very involved in that fanbase, did a lot of my discussion on reddit), has not materialized yet, not enough fans over here, hopefully that changes at some point. I thought at first that it was the open support of Luigi's alleged actions that got me banned, I could be ok with that, I get it, supporting violence and whatnot, I broke the rules, and they were sensible rules more or less, but the longer I look at the current happenings over there, the more suspicious I am that it was because his name came up at ALL, multiple times. That's annoying. That feels less justified.
Also becoming more and more glad it happened when it did. Lot of overt, fascist appeasing censorship going on over there. Like it's not even subtle. There's no ambiguity in it, it's just "this post criticized or disparaged Musk or Trump in some way. (Removed from Reddit)."
[email protected] is the biggest one I've found but it's VERY inactive. You'd be better off going to a Sonic forum like the Sonic Stadium message boards, but those are a little less penetrable than something like reddit because EVERYONE there is a huge, dedicated fan, and it can get really strongly opinionated.
